Hunemeier believes United might struggle to sign Sancho because of his Manchester City past.
Sancho has frequently been linked with a move back to the Premier League this summer, with United putting him at the top of their list of targets, but veteran centre-half Hunemeier - who is set to come up against Sancho as Paderborn take on Dortmund on Sunday - believes his City history could hinder their pursuit.
"He played for Manchester City before if I'm not wrong?" he said, on the Transfer Window podcast.
“So I don't know if he would be happy to play for United then, I don't know how big the rivalry is between these two teams.
"I know there's a rivalry but I don't know how he sees that. But in terms of football, probably his style would definitely suit Liverpool. But it's difficult to tell him what's best for him. He's such a big talent, he could play for every big club in England."
